  That's an issue then.

  EAP-FAST is more than a bit magical.  We've tested it with a bunch of equipment.  But if it fails in the MS-CHAP calculation.. then something bad is going wrong.

  FreeRADIUS has been doing MS-CHAP for almost 20 years.  If that calculation fails, then either the other end is buggy, or the password really is incorrect.
